To WHOM .IT MAY OONOERN: I'

Beit known that I, JOHN SIIELLABERGER, of Shane's Crossing,ivIercerc'ounty, Ohio, have invented a ecrtain new and useful-Tile-Machine; and do hereby declare the' following to be a full, clear,and exact description l thereof, reference beinghad tol the accompanyingdrawing, making part of this specification.V l Ais the boxenreceptacleof a pug-mill, having a shaft, B, armed with tempering-blades C, andprovided with a sviee'p, D, having alhcel orgextension, `D, beyond theshaft, provideduvith a wristE, connected by n l pitma-n, F, with avibrating-armyG', whosclower end is connected to a rod, H, \vl1ieh'terminates in a piston, I, 'that acts in its forward motion to expel thetempered clay Ith'rou'rh suitably-formed orifices J, at Vthe bottom ofone sidecf the chamber Krbencath the box A. l I I '*;"="'The' mchineisftintondocl-to be propelled by horselor other animtllpower, ugap, L",in the frame L permit- -tinjg the passage ofthel team. l t Y i .Mymachine possesses several important features of practical superiority inits construction and arrangement. First. By forming `the crankfarm byanextension, D', o-f the sweep D, Lobviate in a great measure' torsionalstrain upon the shaft B, which isa common cause of breakage m machinesof this class as heretofore constructed. SecondBy placing thc pitmanF'abave the swcepD, and extending it in length, and the lover G, outsidethe path4 of the' horscs,'I reduce by one-half .the lateral strain uponthe said lever, and thereby greatly lessen. the power required' toac'tuvate it., i

Third. The arran'gementlast named also enablesv me to employ aplunger-rod, II, of so great length thapjgg.

requires no joint or guide, and \vill,by its own elasticity, accommodateitself to, the curved vibration of the lever G. l v' v i Y V I Fourth.By the advantageous disposition ofthe partsfo'r strength and eciency, Iam enabled to dispense 'with castings, and thus make my machine verycheap, simple, and easy of manufacture. Having thus described myinvntion, what I claim-as new, and desire tosecure by Letters Patent,is-

' The relative arrangement of the shaft B, sweeps D I), pitman F, leverG, and plunger I, substantially :lsond for the'p'urposes set forth. 1 il In testimony of which invention, I hereunto set myihand. JOHNSHELLABERGER.
